Show renders from our lenses

This script allows you to visualize in advance how a scene will render through some or all of our current lenses for a user-selected sensor size. By default it will use all of the lens files in your path, but you can filter for those containing a specific string in their name.
Dependencies: ISET3d-v4, ISETCam, isetlens
D. Cardinal, 2022
Note: For expediency, we have pre-generated several possible variations of scene and sensor size and placed them as HTML files in the previews sub-folder.

Initialize ISET and Docker

ieInit;
if ~piDockerExists, piDockerConfig; end

Choose Options

sensorSize =6; % (diagonal in mm)
useScene = 'chessSet'; % one of our default scenes
raysPerPixel = 96;
sensorResolution = 400;
% optionally only render matching lenses
lensNameFilter = "";
 
fprintf('Lens Inventory using Scene: %s\n', useScene);
Lens Inventory using Scene: chessSet
fprintf('Sensor Size: %d, rayPP %d, resolution %d\n',...
sensorSize,raysPerPixel,sensorResolution);
Sensor Size: 6, rayPP 96, resolution 400

Read the selected Scene and add a Light

thisR = piRecipeDefault('scene name',useScene);
Read 9 materials and 3 textures..
lightName = 'from camera';
ourLight = piLightCreate(lightName,...
'type','distant',...
'cameracoordinate', true);
recipeSet(thisR,'lights', ourLight,'add');

Set render quality

% Set resolution for speed or quality.
thisR.set('film resolution',[sensorResolution sensorResolution]); % 2 is high res. 0.25 for speed
thisR.set('rays per pixel',raysPerPixel); % 128 for high quality
 
% Pick out a bit of the image to look at. Middle dimension is up.
% Third dimension is z. For the chess set we use a from/to that put the ruler in the
% middle. The in focus is about the pawn or rook.
switch(useScene)
case 'chessSet'
thisR.set('from',[0 0.14 -0.7]); % Get higher and back away than default
thisR.set('to', [0.05 -0.07 0.5]); % Look down default compared to default
case 'cornell_box'
%
end
%thisR.set('aperture diameter',1); % thisR.summarize('all');

Determine the range of object depths in our scene

Note: Getting depth will use pinhole optics, but we use an omni camera with lenses for the rest.
depthRange = thisR.get('depth range');
*** Rendering time for ChessSet: 8.6 sec *** exr2bin done.
%depthRange = [0.1674, 3.3153]; % Chess set distances in meters

Create cameras that use each lens

We get a list of all our lenses, then iterate over it creating a camera object using that lens, and render the same scene through each of them.
allLensFiles = lensC.list('quiet', true);
if ~isempty(lensNameFilter)
lensNames = {allLensFiles.name};
lensIdx = contains(lensNames,lensNameFilter);
lensFiles = allLensFiles(lensIdx);
else
lensFiles = allLensFiles;
end
images = []; % our output images
for ii = 1:numel(lensFiles)
lensFileName = lensFiles(ii).name;
lensFile = fullfile(lensFiles(ii).folder, lensFileName);
fprintf('Using lens #%d: %s\n',ii, lensFile);
thisR.camera = piCameraCreate('omni','lensFile',lensFile);
thisR.set('focal distance',mean(depthRange));
% depending on the film size we'll get
% different fields of view
thisR.set('film diagonal',sensorSize);

Render and display

piWrite(thisR);
try
oi = piRender(thisR,'render type',{'radiance', 'depth'});
oi = oiSet(oi,'name',sprintf('Lens: %s and %d mm sensor',...
lensFileName, sensorSize));
% get a viewable version of our optical image:
img = oiShowImage(oi,-1);
% Load our lens so we can view it
lenses{ii} = lensC('filename', lensFile);
% Set some headers per lens
%fprintf('----------------------------\n');
%fprintf('Rendered using: %s, with focal length: %05.1f',lensFileName,lenses{ii}.focalLength);
% Draw a diagram of our lens into a subplot
[~,fHdl] = lenses{ii}.draw([2,2,1]);
images{ii} = img; % for creating a montage at the end of the script
% show sample output in our subplot
subplot(2,2,2);
imshow(img,'Border','tight');
% plot relative illuminance (into a subplot)
piRelativeIlluminance("lensfile",lensFile,"figure",[2,2,3],...
'sensorSize',sensorSize, 'focalDistance', thisR.get('focal distance'));
 
% plot MTF
%filmwidth_mm=0.01;
filmwidth_mm=.01;
[MTF, ~, ~] = piCalculateMTF('camera',thisR.camera,...
'distances',depthRange,...
'resolution',2000,'rays',1000,...
'filmwidth', sensorSize/1000);
subplot(224);
plot(MTF.cyclespermilimeter,MTF.MTF);
xlabel('cy/mm');
